Trivia / Atelier Lydie & Suelle: The Alchemists and the Mysterious Paintings

• Acclaimed Flop: Upon the game's release, it became an instant hit among players, who praised it for its involved plot and characterization, high-quality music, solid conclusion to the plot of the Mysterious saga, and gameplay that fixed many of the severe issues that had plagued Sophie and Firis. Unfortunately, it was too late; said two games had caused a massive drop in audience interest, and despite an involved 20th anniversary campaign from Gust that advertised Lydie & Suelle as different from past entries, the game's actual sales were atrocious, with its first-week Japanese sales being the worst in the franchise since Mana Khemia 2. However, as Sleeper Hit mentions, the game did not remain a flop for long.
• Milestone Celebration: The game was advertised as commemorating Atelier's 20th anniversary, although in practice it doesn't do anything special to observe it and simply serves as the final Mysterious entry as it would have had it been released any other year.
• No Dub for You: This is the first main line game to be localized without an English-language voice dub, breaking the standard that had been in place since Atelier Iris thirteen years prior. A Youtuber who attended the Nelke press event was told by a PR manager from Koei Tecmo that their player data showed most players just played the games in Japanese anyway, hence they were able to speed up the localizations by dropping the production of the largely unused dubs and also saving money on the localization cost. As it is, since Atelier Rorona, the dubs were already known to be very barebones with most of the game largely unvoiced outside of battle lines and key cutscenes.
• No Export for You: The Vita version never left Japan due to the state of the market for Vita titles in the West. While understandable, this did leave Western fans who collected the Mysterious series on the Vita out of luck on finishing the set.
• Sleeper Hit: After a first week of poor sales, the game was written off as an Acclaimed Flop. However, thanks to good word of mouth, Lydie & Suelle eventually tracked to 180,000+ units sold in Japan and Asia after 4 months. This meant that Lydie & Suelle eventually became the most successful entry of the Mysterious saga and one of the best selling Gust games ever made.
